The dungeon's western entrance is west of the Lava Maze, level 42 Wilderness in a metal fenced area containing lesser demons. This entrance leads to a small area containing only poison spiders and the lever to enter the King Black Dragon'slair. This part of the dungeon covers level 42 to 43 Wilderness.

The dungeon's eastern entrance is in the centre of the Lava Maze, level 42 to 43 Wilderness in a metal fenced area. This entrance leads to an area containing more monsters and a single Runite ore rock. This part of the dungeon covers level 41 to 47 Wilderness.

Although the western surface entrance is used to reach the poison spider area and lever to the King Black Dragon Lair, on the map, this area appears to be in the eastern part of the dungeon. Similarly, eastern surface entrance appears to lead to the western part of the dungeon. This reversal is similar to some of the entrances to the Ardougne Sewers. It is not known if this is a mistake by Jagex or is deliberate.
